supported by the LS100. Hardware flow control method controls data communication flow by sending signals back and forth between two connected devices.
The purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP connection state by using serial port signal. The DTR is a
The DTR option can be set to one of three types: always high, always low or show TCP connection. If the DTR behavior is set to show TCP connection, the state of the DTR pin will be maintained high if the TCP connection is established.
The DSR option can be set to one of three types: none, allow TCP connection only by high or open/close TCP connection. Allow TCP connection only by HIGH is valid only if host mode is TCP server or equivalent. If this option is set, the incoming TCP connection request will be accepted only when the DSR signal is high state. Open/close TCP connection is valid only if the host mode is a TCP client or equivalent. If the DSR behavior is set to open/close TCP connection, the high state of the DSR pin will make the LS100 send a connection request to the specified destination host, whereas the low state close a connection.

10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.
Therefore, you have to set
If users want to send the series of characters into a packet, serial device attached to the LS100 should send characters without time delay larger than
